Technical Basis
A review of available sources identified rat and mouse LD50 acute toxicity for various routes (oral, intraperitoneal, intravenous), and an OEL-STEL (Romania). Data sources were selected according to the hierarchy listed in Table 3.1. Toxicity data were selected according to type of exposure, species, and route according to the hierarchies stated in Sections 3.3.1, 3.3.2, and evaluated using factors in Tables 3.2, 3.3, and 3.4. The most preferred species and route data, rat oral LD50, was selected as the TEEL-3 basis. The OEL-STEL (Romania) was selected as the TEEL-1. The TEEL-2 value was derived according to Table 3.5.
• PAC-1 = TEEL-1 = OEL-STEL (Romania, 20 mg/m3)
• PAC-2 = TEEL-2 = TEEL-3/6
• PAC-3 = TEEL-3 = Rat oral LD50 (1900 mg/kg)
This review generated a PAC-1 value inconsistent with Rev. 29A, and PAC-2 and PAC-3 values consistent with Rev. 29A. The Rev. 29A TEEL-1 was derived from the TEEL-2 (Table 3.5), while the current basis is an exposure limit, the OEL-STEL (Romania). The Rev. 29A and current TEEL-2 and TEEL-3 methodology and values remain consistent.
